For many years mathematicians, scientists, engineers and others
interested in mathematics have played "year games" via e-mail and in
newsgroups. We don't always know whether it is possible to write
expressions for all the numbers from 1 to 100 using only the digits
in the current year, but it is fun to try to see how many you can
find. This year may prove to be a challenge.
As with many games, the rules for the Year Game can
vary slightly. Teachers may wish to use different rules in their own
classrooms. This Web page is intended for students in grades three
through twelve with a general knowledge of mathematics.
Our rules: use the digits in the year 2007 and the
operations +, -, x, ÷,
^ (raised to a power),
sqrt (square root),
and
! (factorial),
along with grouping symbols, to write expressions for
the counting numbers 1 through 100. This year we will also allow the
use of decimal points and double-digit numbers. Please read and
follow the rules carefully if you wish
to have your solutions posted on this site.
Teachers may print out worksheets for students to record
their findings, or may print sheets of manipulatives for students to use.
